FLOOR-JOINT FOR WATER-CLOSET BOWLS.

isoaica.

Specification of Letters Patent. Patnged Apr. 29, 1919.

Application filed August 7, 1918. Serial No. 248,736.

To all whom t may concern Be it known that I, CHARLES C. HINGH- MAN, a citizen of the'United States, residing in Pottstown, Montgomery county, Pennsylvania, have invented an Improved Floor-Joint for Water-Closet Bowls, of which the following is a specification.

My invention relates to the floor connections or joints between watery closet bowls and soil pipes; and the object ofmy invention is to provide animproved construction whereby I am enabled to secure an absolutely gas, airand water-tight joint between the bowl and the soil pipe. In addition, I have provided a structure in which the compression of the gaskets to insure the tightness of the desired joint is applied below the floor, with nuts for taking up the bolts to effect this compression accessible entirely from the room in which the closet is located. My improved construction provides a fluid-tight connection between the joint and the bowl and between the joint and the soil pipe.

These and other features of my invention are more fully described hereinafter, reference being had to the accompanying drawings, in which:

Figure 1, is a sectional view of a closet foot provided with my improved joint, and

Fig. 2, is a sectional perspective view of the members making up the improved joint constituting my invention.

In the drawings, 1 indicates the discharge leg of a water closet bowl or other similar fixture, having the usual depending flange 2 adapted to fit into the receiving end of a soil pipe 3, and the usual flanged foot 4 surrounding said discharge leg and which may rest upon a floor slab (not shown), or upon the iioor 5, as indicated in the drawings.

In the recess 6 formed by the flanged foot 4 and directly adjacent the depending flange 2, I may provide a gasket 7 of resilient or elastic material, which engages the under side of the foot 4. Below this gasket I preferably provide a ring or collar 8, having a` fiange 9; the flanged portion being in contact with the gasket 7, while the Wall of the ring preferably` tapers outwardly with respect to the soil pipe so as to provide internally thereof a concavity which, when said ring 8 is disposed adjacent the soil pipe, is substantially wedge-shape in cross section, as clearly illustrated in the drawings. The

flange 9 of the ring may rest upon the soil pipe or overhang the latter.

Disposed between the soil pipe 3 and the ring 8 and located in the wedge-shaped space provided by the latter, is a gasket of suitable elastic material 10, and in order that this gasket may be forced into the space between the ring and the soil pipe for the purpose of making a fluid-tight joint between said parts and, in addition, causing the ring to compress the gasket 7, I provide a collar 11 adapted to engage said gasket 10,' which collar has ears 12, to which stud bolts 13 or other fastening means may be secured. Such fastening means, the stud bolts for instance, are adapted to pass through apertures 14 in the foot 4 and receive at their upper ends nuts 15 whereby said collar 11 may be compressed against the gasket 10, thereby sealing the joint and holding the several parts constituting my improved connection securely in place.

. Upon assembling the structure constituting my invention, it will be seen that the act of raising the ring 11 by drawing up on the fastening means, (the bolts 13 for instance, by turning the nuts 15,) first lifts the ring or collar 8 against the washer 7; making the desired gas or fluid-tight connection with the closet bowl, while continued movement of said bolts by turning the nuts causes the ring 11 to compress the wedgeshaped gasket 10 between said ring or collar 8 and the soil pipe, and complete the gas or Huid-tight connection at such point.

From the foregoing description and an examination of the accompanying drawings, it will be seen that I have provided by my invention an extremely simple means for effecting the necessary gas-tight connection between a soil pipe and water closet `bowl or similar fixture and which is, at the same time, of a character permitting easy removal of the fixture when and if desired.

It will be understood, of course, that changes may be made in the various details of construction without departing from my invention, and that while definite embodiments of my invention have been shown in the accompanying drawings and described with more or less particularity, I do not wish to be limited to the construction disclosed; desiring to claim any equivalent construction capable of performing the function for which the improved iioor joint for water closet bowls or other similar fixtures second gasket, and securing means connected `to said collar and in engagement with the water closet bowl whereby said parts may be retained in place and the gaskets compressed to insure a fluid-tight joint between the bowl and soil pipe.

2. The combination with a water closet bowl or similar fixture having a depending flange, and a soil pipe receiving such flange, of an annular gasket surrounding said depending flange, a ring surrounding the soil pipe and engaging said gasket; the wall of said l ring being outwardly flared and so disposed with respect to the soil pipe that a wedge-shaped space is provided between the saine and the soil pipe, a gasket disposed between said ring and soil pipe and engaging both parts, a collar surrounding the soil pipe and engaging the thick edge of said gasket, and securing means carried by said collar and engaging the foot of the bowl whereby said parts may be retained in place and the gaskets compressed to insure a fluidtight joint between the bowl and soil pipe.

3. The combination with a water closet bowl or similar fixture having a depending flange, and a soil pipe receiving such flange, of a gasket surround-ing said flange, a flanged ring surrounding the soil pipe and engaging said gasket; the wall of said ring flaring outwardly whereby a w,edgeshaped space is provided between the saine and the soil pipe, a gasket fitting said wedge-shaped space and engaging the ring and soil pipe, an annular collar in engagement with the thick edge Voli said gasket, and securing means carriedby said collar and engaging the foot of the bowl or other fixture whereby said parts may be retained in place and the gaskets compressed to insure a fluid-tight joint ,betweenfthebowl and soil pipe.

4. The combination with a water closet bowl or similar fixture having a depending flange, and a soil pipe receiving such flange, of an annular gasket surrounding said depending flange, aA flanged ring surrounding the soil ypipe and engaging said gasket; the wall of said ring flaring outwardly whereby a wedge-shaped space is provided between the same and the soil pipe, a gasket in said wedge-shaped spacefengaging the soil pipe and ring, a collar surrounding the soil pipe and contacting only with the thick edge of said gasket, and securing means carried by said collar and engaging the -vfoot of the ture whereby said parts may be retained in place and the gaskets compressed to :insure a fluid-tight joint between the bowl and said soil pipe.

5. rlhe combination with a water closet bowl or similar fixture having a depending flange, and a soil pipe receiving such flange, of an annular gasket surrounding said depending flange, a flanged ring surrounding the soil pipe and engaging said-gasket.; the wall of said ring flaring outwardly whereby a wedge-shaped space is provided between the same and the soil pipe, a gasket in said wedge-shaped space engaging the soil pipe and ring, a collar surrounding the soil pipe and having a portion in engagement with the thick edge of said gasket, bolts vcarried by said collar and passing through the foot of the fixture, and nuts for Vtaking up` said bolts whereby said parts may be retained in place and the gaskets compressed to insure a fluid-tight joint between the bowl and soil pipe.
